Issues with the Cupper Theme

I had just started with Hugo and loved the Cupper Theme. As per the instructions given in the github page GitHub - zwbetz-gh/cupper-hugo-theme: An accessibility-friendly Hugo theme, ported from the original Cupper project. I had downloaded the theme using the git command as appropriately and it was successful as well.

git submodule add themes/cupper-hugo-theme
git submodule update --remote --merge

However when I ran the server with ‘hugo server -D’, it get the following error on the console.

λ hugo new posts/
Error: add site dependencies: load resources: loading templates: "C:\hugoPractices\hugo-cupper-theme-test\themes\cupper-hugo-theme\layouts\partials\head.html:14:1": parse failed: template: partials/head.html:14: unclosed action

And this is what I see in line 14 and 15

    {{ $summary := trim (.Summary | plainify | htmlUnescape) 
  | default .Title }}

I tried bringing the line 15 to 14 (towards the end) but that gave various different set of errors.

Can someone advise what went wrong? I did not do any changes except downloaded the theme via git into my hugo project.

It seems that you are using an older version of Hugo.

Support for newlines in template functions was introduced in v.0.81.0.

You need to update your Hugo installation.


Thank you @onedrawingperday . However i just installed it afresh from Chocolatey. I expect that it should have pulled out the latest repo. Right ?

λ hugo version
Hugo Static Site Generator v0.80.0-792EF0F4 windows/amd64 BuildDate: 2020-12-31T13:37:57Z

Little I had a clue that it was not the up to date. Let me check and update it.

It was my bad. I had two different versions of Hugo installed. I had an earlier version installed elsewhere (older version - 0.80) which was set in the PATH environment variable. Today I had installed it via Chocolatey and it was not set in the path, and hence it caused the confusion when I simply invoked ‘hugo’ it took the older version.

After I updated the PATH environment variable with the latest version of hugo with the following steps,it solved the problem.

Prefixing the latest HUGO path in the PATH env variable, so that it gets picked up.

C:\raghs\prfsnl\hugoPractices\hugo-cupper-theme-test (master)
λ set PATH=C:\ProgramData\chocolatey\lib\hugo\tools;%PATH%

Later when I invoke hugo on the same terminal/command prompt, it is verifying the latest.

λ hugo version
hugo v0.83.1-5AFE0A57 windows/amd64 BuildDate=2021-05-02T14:38:05Z VendorInfo=gohugoio

Also, it solves the problem. I dont get any errors when I run the hugo server.

C:\raghs\prfsnl\hugoPractices\hugo-cupper-theme-test (master)
? hugo server -D

Thanks for bringing this up @itsraghz. I’ll update the README here and in my other themes with the new minimum hugo version required.

Thanks @onedrawingperday for pointing out the solution.
